Read Abstract +

In this work, we demonstrate the establishment of a self-injection locking threshold in a quantum dot (QD) comb laser with a Fabry-Perot cavity and an external feedback loop. This process involves controlling injection power and polarization to inject a controlled fraction of lasing power back into the QD laser source. The study is focused on the single line self-injection locking effects. The self-injection locking process was characterized by a self-injection locking threshold power (P_SIL) and a locked power (P_locked). The self-injection locking process begins from the threshold power P_SIL and followed by a magnified enhancement till it reaches the locked power (P_locked). Once in the locked region, the enhancement effect starts to stabilize and is only weakly influenced by injection power. The established threshold provides a distinctive condition for the measurements of the modified optical properties of the coupled cavity system. Additionally, the locked single lines tested at different currents indicated a very broad spectral coverage which are much larger than the original bandwidth of free running QD laser.
